[web-devel] [persistent] [postgres] PoolExhaustedException in Persistent

[Max Cantor]

Hi,

I'm getting PoolExhaustedException's on persistent-postgres.  I'm on persistent 6 and yesod 9.  any ideas where to start looking for a source?  

my runDB is straight out of the foundation:  

runDB f = liftIOHandler $ fmap connPool getYesod >>= Settings.runConnectionPool f  

thanks, 
max
